change php code from curl to php header to search return url exist or not..

Project Budget $0-$50 USD I have small php file reads the static file that contains urls (see attached). Current php code checks urls if url file exist or not by reading file_sources.txt. Current code uses curl but I am not happy with curl results and I am not going to use it. (do not try to fix curl I don't want to use it) It gives sometimes wrong reaction and determine file exist when it is not. Code I want you to change is from curl to code giving you below. If you know how to use php, It will take about 1-2 hours for you to change. You will see [login to view URL] attached. You might require to upload and unpack this to your website and edit [login to view URL] change path. Upload this php to your website to see if you can understand code. give 777 permission to project and robot folder before run [login to view URL] $path = '/home/mywebsite/www/1/staticfiles'; $programpath = '/home/mywebsite/www/1/robot'; I would like to use this code instead of curl therefore delete any code related curl !!!!!!!!!!!!!!!!!!THIS CODE WILL BE INJECTED TO [login to view URL] AND REMOVE CURL !!!!!!!!!!!!!!!!! <?php function UR_exists($url){ $headers=get_headers($url); return stripos($headers[0],"200 OK")?true:false; } if(UR_exists("[login to view URL]")) echo "file exists"; else echo "file does not exist"; ?> What does [login to view URL] do (attached) 1) Reads static files folder 2) Search any static files contains bigger than 2kb. We don't need files less than 2kb because these static files doesn't have url content so we don't worry about them. for example we will have 100.000 files but we only have 60.000 static file have urls creates [login to view URL] 3) after search for more than 2kb files. Script search for every individual file and get static file name and file url inside by using regex and save as [login to view URL] (see attached) this is final process before search urls file. 4) Program start to search every url by referencing [login to view URL] using curl return if file exist or not. 5) Only 404 results will be written on logs files you will see these files in php file. we don't worry about 200 results. note: there is also limit option in [login to view URL] where I can change currently it is 10 means at the same time this code checks 10 url
